MARINE INVERTEBRATA OF GRAND MANAN. , 31 



depressed line cohimences, numiiig on the remaining length of the bod}^ The 

 l)nuuhi;u arc on tlic llrst two segments. The neck is provided with a ring of e^-e- 

 spots, numerous and variable in size, under the hiljia of the tentaculifei'ous disk. 

 On tlie 22d sogiiient, at the right side, just above and Iteliind tlio sujterior pinna, 

 arise two long tube-like cirri, which in one of my specimens are filled with eggs (?). 

 It inhabits a tube of a thin leathery structure. 



I at first considered the animals above described as immature, on account of the 

 presence of e3-es "at the neck ; as Prof Agassiz states such to be the case in young 

 specimens of his Itrchdla fuhjhlu. (See Bost. Proc, iii. 191.) But having, among 

 many specimens, observed none larger or further developed, and considering most 

 of the remaining characters above mentioned as important, 1 have been led to 

 propose a new genus for the reception of the species. 



LuMARA FLAVA, St., n. s. Of a bright-yellow color; branchia? with 6-8 rami, and 

 a few short processes on the sides of their rings. Length one and a half inch ; 

 breadth, 0.11 inch. Tubes thin, of a light-yellowish color, usually with pebbles 

 attached to the outer surface. Dredged in 35 f in the Hake Bay. 



Terebella brunnea, St., n. s. This species is large, of a uniform, dark, reddish- 

 brown color; segments about 50; acicula; of the anterior feet rather short; the 

 ventral shields on the first eight segments oblong, transverse, and rather narrow. 

 Tentacula large and very numerous, brownish ; branchiae in three pairs, with 7-1 2 

 rami to each, those of the first pair being most numerous. Length al)out five 

 inches; greatest breadth three-tenths of an inch. It inhabits thick-walled tubes, 

 formed of mud and sand, which arc found in great numbers on the under sui'faces 

 of large stones, near low-water mark. 



The uncinate setge in this species are very variable in shape. They are of the 

 same type as those of T. parvula, Leuckart, as figured in Wiegm. Archiv, 1849, 

 Taf. iii. f G, but are much more elongated and projecting above. 



T. cirrata, Cuv. Leuck., 1. c. This species differs from the preceding in its 

 smaller number of rami in the braiichiai, in the rhomboidal shape of the last ventral 

 shields, and in the bright-yellow color of the anterior ventral surface. The unci- 

 nate setcVJ conform generally to the same type as those of T. hruunea, and though 

 they have sometimes slight denticles besides the upper frontal tooth, 1 have never 

 met with any precisely like those of T. cirrata figured by Leuckart (1. c, fig. 5). 

 The aciculoe are longer than those of the preceding species, and widened near their 

 extremities, which taper to fine hair-like lashes. 'My specimens are about three 

 inches in length, with nearly seventy segments. They were all found in deep 

 water, chiefly on shelly bottoms, in 20-40 fathoms. 



Clymene lumbricalis, St. (nou Aud. et Edw.) Sahella lumhricalis, 0. Fabr., F. 

 G., p. 374. Tubes adherent to stones, shelLs, etc., in deep water. 



M A R I C L .E . 



Arexicola piscatoru.v, Cuv., Regno Anim., etc. Common on sandy shores above 

 low-water mark, especially where there ai'e scattered boulders. 



SiruoNOSTO-MUM ASi'ERUM, St., u. s. Body slender, thickest anteriorly behind
